To 1/// whom it may oonccrn:

le it known, that I, Winch-in ll. la'i'rnn sex, a citizen of the United States, residing at New Orleans, in the parish of Orleans and Stuteflof Louisiana have invented certain new and useful Improvements in Roof- Ulips, of which the following is a full, clear,

' and exact description This invention relates to fasteners for retaining roof sheets to the purllns of a root. As is well known, the usual munuer of fastening roof sheets to the purlins is by means. i

of a clip which is attached to the purlin; a

rivet passes through the clip and serves to secure the roof sheet to the clip. it has heretofore been proposed to permanently unite the clip and rivet and to so position the rivet upon the clip that the purlin acts its a support for the rivet while the some is being passed through the roof sheet and upset to fasten these parts together, this construction being desirable since it permits the roof sheets to be more quickly and readily fastened in place. It is the purpose of this invention to provide an improved form of fastener of this character which can be used with purlins whose flanges are directed toward the peak or eaves of the roof of a building and which will rigidly secure the roof sheets in position against lateral movement in either direction. .Itjs also the objectof the invention to provide a cheap and simple form'of fastener which maybe manufactur'ed at a comparatively low cost.

With these objects is. view, the invention consists in providing a substantially U- shapcd clip having on v offset extension through which the rivet is passed and secured thereto by brazing or in any other suitable manner, the head of the rivet fitting 5 in thespace provided by the otl'set portion whereby when the clip is secured to the flange of the purlin, the head of the rivet will rest upon the same end he supported thereby while the roof sheet is being fastened to the 'rivet. Two such clips may be utilizedto secure a roof sheet to a purlin. One of these clips fits over the flange of the 1 purlin as described while the other clip is oppositely disposed and has its free log abuttin against the vertical web of the purlin en has its offset extension extending over the flange so that the head of the rivet also rests upon the top flange of the pnrlin.

When the roof sheet is fastened to both rivets, these clips, due to their engagementwith the purlin, will prevent the roof sheet.

from lateral movement in either v direction,v and will therefore provide a' very secure A means for tasteiung the roof sheets in position.

ig. 4 shows'a clip abutting against the f vertical web of the purlin, the clip which As is usual in root constructions, the-roof sheets are supported upon purlins which run transversely to the rafters 1 of the building, one of these rafters being shown is a perspective view of the clip;

fits over the flange of the purlin being shown in Fig. 1. 'The purlins 2 generally consist 4 of strips of channel iron andfcomprise a vertical web 2 and flanges 3. Thcpurlins.

are-usually positioned so that their flanges are pointed toward the peak of the roof as lnFig. 1. T he roof sheets which have been designated 4- are supported upon the p'urlins and are fastened thereto by means of rivets which pass through clips which are adapted to he secured to the purlins. These clips are in accordance with this 1nvention constructed from a flat piece ofmetal which is stamped into the form shown in Fig. 5 providing n U-shaped part designated 5 undan offset extension 6, the

offset extensionbeingconnectcd to one of the of the U-shupeu part-by means of an 'angularly-disposed portion 7. The amount of offset is sufficient, to provide a space for the head 8 of a rivet 9, the shank of which passes through a suitable opening in the offset portion of the clip. The rivet is permanently secured to the offset extension which may be accomplished by brazing the shank of the rivet within the serves as a block or anvil ing fastened to its shank.

Where the anges of the purlins point toward. thepeak of the house, the clips are aflixed to the top flanges of the purlins as shown in Fig. 2, the U-shaped portion of the clip fitting over the end of the flange, WhllG- the offsetexteasionis directed toward the 'web of the flange so that the head of the rivet "rests directly upon the top. flange. In this position the purlin to support the head of the rivet while the roof sheetis be- This isaccon'iplished by placing the roof sheet over the rivet as is shown in Fig. .2 and then forcing the end of the shank of the rivet through the roof sheet, the; roof sheets be ing made of comparatively thin sheet metal to give it strength. A head is then formed on the shank of the rivet with a pneumatic riveter or in any other-desired manner.

Where the flanges of the purlins point toward the eves of the building, theclips are arranged as is shown in Fig. 4. In this construction the end of the free leg of the U-shaped portion abuts against the vertical web of the purlin and the head of the rivet rests 'liponthe top flange. The roof sheets are fastened to the rivets in the manner to prevent The through said the roof sheets from being raised from the purlins, additional clips are supplied which are fitted over the flange in.the manner shown in Fig. 2, or as is shown in dotted lines'in Fig. i. It is desirable to proportion the clips so that the rivets of both clips will he in alinenient and will pass through the top of the. convened portion of the Corrugatcd roof sheets. if the root sheets are not corrugated this is not important.

I claim:

1. A roof clip having two legs adapted to embrace a part of a purlin, an extension rising from one leg to engage a portion of a roof sheet elevated from the purlin, and a rivet whose shank projects upward sheet and having a head extending downward and adapted to rest directly upon the purlin.

2. A roof clip having two legs adapted to enilnace a. part of a purlin, an extension which rises rein one'leg extension to engage the roof I p to engage a por-' tion oi a roof sheet elevated from thepurlin i p a head e2o5ending adapted to rest directly:
